Properties of Torrefied Biomass and Torrefied Pellet

This paper reviews the torrefaction biomass properties, which have to be measured both laboratory and pilot scales. In laboratory scale, the products from torrefaction process are called torrefaction biomass. The properties usually determined in laboratory scale are heating value, grindability, and energy yield. In pilot scale, the torrefi ed biomass is formed into pellet and called torrefi ed pellet. The important properties of torrefi ed pellet are durability, hydrophobicity, and bulk density. The standards procedure used for testing the torrefi ed biomass properties and torrefi ed pellet are described in this review. Finally, the effect of torrefaction temperature on the properties of torrefi ed biomass and torrefi ed pellet is explained.
